On the other hand, in vehicle air conditioning equipment 10, carry out under the situation of cooling down operation, by switching to operator scheme by console switch, under the drive actions of drive source 20, driving shaft 38 in the opposite direction rotates, and first gear 44 is being rotated counterclockwise direction (direction of the arrow C 2 of Fig. 7) upward with driving shaft 38 rotations.As a result, second gear by with the engagement of first gear 44, (direction of the arrow D2 of Fig. 7) goes up rotation in the clockwise direction, and, air door gear 82 by with the engagement of second gear 46, (direction of the arrow E 2 of Fig. 7) goes up rotation in the counterclockwise direction.
Thus, axle of the air door 50 is rotated counterclockwise (direction of arrow E 2) by the driving force from drive source 20, and the air blender door 18 by rack member 32 and planetary gear 86 engagements moves to downside towards heater core 16 along guiding wall 34a and guiding wall 34b.
The result, owing to stopped by air blender door 18 through the stream of the air between evaporimeter 14 and the heater core 16, air (cooling air) that provide from blower fan and that passed through evaporimeter 14 does not flow to heater core 16 sides, and by the pipelines in the housing 12 flow directly to exit opening and from, for example can be near the passenger's of vehicle face the outlet port of blow out air, be blown in the vehicle car.
In the above described manner, according to present embodiment, be delivered in the driving force transmission mechanism 22 of the air blender door 18 that is contained in the housing 12 in the driving force in self-driven source 20 in the future, a kind of structure is provided, it comprises second gear 46 that is meshed and further is meshed with the axle of the air door 50 that makes air blender door 18 rotate with first gear 44 that is connected to drive source 20, and this second gear 46 is rotatably supported with respect to gear stand 48.
Result as said structure, even in housing 12, the air blender door 18 that drive source 20 and quilt rotate from the driving force of drive source 20 is set under the situation of position separated from one another, and the driving force of exporting from first gear 44 can reliably and effectively be passed to axle of the air door 50 by second gear 46.And, owing to gear stand 48 (wherein second gear 46 is supported) can easily be cut apart housing 26 with respect to first and drive source 20 is fixed, so, the simplicity of the assembling of the vehicle air conditioning equipment 10 that comprises driving force transmission mechanism 22 can be improved.
In addition, because by by first gear 44, second gear 46 and the axle of the air door of forming driving force transmission mechanism 22 50 gear mechanisms that define, the driving force of drive source 20 is delivered to air blender door 18 effectively, so, air blender door 18 can carry out change action with high accuracy, and can be controlled the mixed proportion of cold air and hot-air by air blender door 18 accurately.
In addition, because the axle groove 78 by gear stand 48 inserts axle of the air door 50, kept constant distance between second gear 46 that in axle of the air door 50 and gear stand 48, supports, so, the axle of the air door 50 and second gear 46 being separated from each other away from each other can be avoided.More specifically, can avoid following problem: the mobile release that causes the engagement between them on direction away from each other owing to the axle of the air door 50 and second gear 46, thus the driving force that causes second gear 46 is not passed to axle of the air door 50.In other words, avoided the variation of the engagement situation between second gear 46 and the axle of the air door 50.
As a result, can be delivered to axle of the air door 50 reliably from the driving force that drive source 20 is delivered to second gear 46, be made it possible to control the driving of air blender door 18 thus through first gear 44.
The vehicle according to the invention air-conditioning equipment is not limited to above-mentioned embodiment.Should be understood that, can carry out various changes and modification to the present invention in the situation that does not depart from invention scope defined in the appended claims.
